We present muon spin rotation and relaxation ($\mu$SR) results for chalcogenide spinels CuCr$_2$X$_4$ with X= S and Se. Both compounds are known as ferromagnetic metals with high Curie temperatures. Our $\mu$SR and magnetization data show clear signa

A detailed study of the preparation of poly and single crystals of the MnCr2S4 ternary spinel and their structural and magnetic characterisation are reported. X-ray diffraction data for the polycrystals show a nearly stoichiometric chemical compositi

Understanding the exotic properties of quantum materials, including high-temperature superconductors, remains a formidable challenge that demands direct insights into electronic conductivity. Current methodologies either capture a bulk average or nea

Single crystals of the Fe1-xCuxCr2S4 system with substitution of Cu for Fe x = 0.4, 0.5, and 0.6 have been succesfully grown using the chemical transport reaction method. Bromine was used as a transport agent. Wave-length dispersive spectroscopy anal

Electrical manipulation of antiferromagnetic states, a cornerstone of antiferromagnetic spintronics, is a great challenge, requiring novel material platforms. Here we report the full control over antiferromagnetic states by voltage pulses in the insu

We report the structural and magnetic properties of high-quality bulk single crystals of the kagome ferromagnet Fe$_3$Sn. The dependence of magnetisation on the magnitude and orientation of the external field reveals strong easy-plane type uniaxial m

Magnetization reversal in ferro- and ferrimagnets is a well-known archetype of non-equilibrium processes, where the volume fractions of the oppositely magnetized domains vary and perfectly compensate each other at the coercive magnetic field. Here, w

The cubic spinel FeCr2S4 has been receiving immense research interest because of its emergent phases and the interplay of spin, orbital and lattice degrees of freedom. Despite the intense research, several fundamental questions are yet to be answered

Polarization- and temperature-dependent Raman data along with theoretical simulations are presented for the Kagome ferromagnet Fe_3Sn_2. Eight out of nine expected phonon modes were identified. The experimental energies compare well with those from t

Magnetic materials with competing magnetocrystalline anisotropy and dipolar energies can develop a wide range of domain patterns, including classical stripe domains, domain branching, as well as topologically trivial and non-trivial (skyrmionic) bubb
